Abstract

Subject matter disclosed herein may relate to reconstructing wireless signal packets and may relate more particularly to reconstructing wireless signal packets from iterations of the wireless signal packets repeatedly transmitted by a transmitter device.

First claim

What is claimed is:

1. A method comprising:
receiving, at a receiver device, a plurality of iterations of a particular wireless signal packet repeatedly transmitted from a transmitter device;
lowering a power state of the receiver device while receiving one or more portions of the particular wireless signal packet that have already been processed at the receiver device;
wherein the receiving the plurality of iterations of the particular wireless signal packet includes, for at least a second iteration of the plurality of iterations and following the lowering the power state of the receiver device, elevating the power state of the receiver device responsive at least in part to receiving a header of the particular wireless signal packet; and
reconstructing the particular wireless signal packet from processed portions obtained from the received iterations of the particular wireless signal packet.

2. The method of claim 1 , further comprising processing, at the receiver device, portions of the particular wireless signal packet, wherein the processing includes detecting, demodulating and/or decoding the portions of the particular wireless signal packet, and wherein the particular wireless signal packet is complete and/or unfragmented.

3. The method of claim 1 , wherein the elevating the power state of the receiver device responsive at least in part to the receiving the header includes elevating the power state a determined period of time following reception of the header based at least in part on the received one or more portions of the particular wireless signal packet that have already been processed at the receiver device.

4. The method of claim 1 , wherein the lowering the power state of the receiver device includes power-gating at least a non-volatile memory of the receiver device.

5. The method of claim 4 , wherein the lowering the power state of the receiver device further includes providing power to at least an analog front end of the receiver device and an oscillator of the receiver device.

6. A method, comprising:
receiving, at a receiver device, a plurality of iterations of a particular wireless signal packet repeatedly transmitted from a transmitter device;
lowering a power state of the receiver device while receiving portions of the particular wireless signal packet that have already been processed at the receiver device;
wherein the receiving the plurality of iterations of the particular wireless signal packet includes, for at least a second iteration of the plurality of iterations and following the lowering the power state of the receiver device to receive one or more of the portions of the particular wireless signal packet that have already been processed at the receiver device, elevating the power state of the receiver device responsive at least in part to identifying particular location identifier content within the particular wireless signal packet; and
reconstructing the particular wireless signal packet from processed portions obtained from the received iterations of the particular wireless signal packet.

7. The method of claim 6 , wherein the elevating the power state of the receiver device responsive at least in part to identifying particular location identifier content within the particular wireless signal packet includes elevating the power state responsive at least in part to identifying one or more specified code sequences embedded within the particular wireless signal packet.

8. The method of claim 6 , wherein the elevating the power state of the receiver device responsive at least in part to identifying particular location identifier content within the particular wireless signal packet includes elevating the power state responsive at least in part to monitoring reception of the portions of the particular wireless signal packet via tracking one or more code sequences having specified correlation properties embedded within the particular wireless signal packet.

9. A receiver device, comprising:
an analog front end to receive a plurality of iterations of a particular wireless signal packet repeatedly transmitted from a transmitter device, wherein the particular wireless signal packet is complete and/or unfragmented;
a power management circuit to lower a power state of the receiver device during receipt by the analog front end of one or more portions of the particular wireless signal packet to have already been processed at the receiver device;
wherein, for at least a second iteration of the plurality of iterations of the particular wireless signal packet and following a lowering the power state of the receiver device by the power management circuit, the power management circuit to elevate the power state of the receiver device responsive at least in part to receipt by the analog front end of a header of the particular wireless signal packet; and
at least one processor to reconstruct the particular wireless signal packet from processed portions obtained from the received iterations of the particular wireless signal packet.

10. The receiver device of claim 9 , further comprising protocol implementation circuitry, wherein the analog front end and/or the protocol implementation circuitry to process portions of the particular wireless signal packet, wherein, to process the portions of the particular wireless signal packet, the analog front end and/or the protocol implementation circuitry to detect, demodulate and/or decode the portions of the particular wireless signal packet.

11. The receiver device of claim 9 , wherein, to elevate the power state of the receiver device responsive at least in part to the receipt of the header, the power management circuit to elevate the power state a determined period of time subsequent to reception of the header based at least in part on the received one or more portions of the particular wireless signal packet to have already been processed at the receiver device.

12. The receiver device of claim 9 , wherein, to receive the plurality of iterations of the particular wireless signal packet, the power management circuit to, for at least a third iteration of the plurality of iterations and subsequent to the lowering of the power state of the receiver device by the power management circuit to receive one or more of the portions of the particular wireless signal packet to have already been processed at the receiver device, elevate the power state of the receiver device responsive at least in part to identification at the receiver device of particular location identifier content within the particular wireless signal packet.

13. The receiver device of claim 12 , wherein, to elevate the power state of the receiver device responsive at least in part to the identification of the particular location identifier content within the particular wireless signal packet, the power management circuit to elevate the power state of the receiver device responsive at least in part to identification at the receiver device of one or more specified code sequences embedded within the particular wireless signal packet.

14. The receiver device of claim 12 , wherein, to elevate the power state of the receiver device responsive at least in part to the identification of the particular location identifier content within the particular wireless signal packet, the power management circuit to elevate the power state of the receiver device responsive at least in part to correlation at the receiver device of one or more code sequences having specified correlation properties embedded within the particular wireless signal packet.

15. The receiver device of claim 9 , wherein, to lower the power state of the recei
